My Doctor Recommended I Start Birthcontrol And I Wasn't Really

my doctor recommended I start birthcontrol and I wasn't really sure if I wanted to because I heard it makes you gain weight and all that. But he prescribed it so I had it at my house. I was 3 days late on my period and was supposed to go visit my boyfriend that week and was scared I was going to start my period close to when I was going and read online taking birth control can delay your period. So I took it and when I went to see my boyfriend I was still taking it. He came in me 6 times though and I wasn't taking the pill around the same time everyday. And the last day I was there I forgot to take it. I was on the pill for a total of 8 days and haven't taken it for 2 days now. I started bleeding today so I'm curious if that just means I'm not pregnant or is there still a chance?
